Update: problem fixed! See post 10 for details.
After months of trying to sell my Speed6, I just decided to keep it. But before I attempted to sell it, I put my stock suspension parts back on (except the endlinks). After which I heard a rear clunking noise over bumps and slightly in some turns. After going to the dealer to try and find the problem, they told me it was probably because of the AWR rear endlinks. While it seemed like reasonable claim, it turned out to be complete crap. I ended up buying and installing ac-delco endlinks but yet the clunk was still there.
Then I remember when I was putting the rear shocks back in, I had trouble with getting the bolts in. It seemed like the threads for the holes were screwed up because the bolts kept going in sideways. I applied extreme force and after 4 hrs, they were back on. Anyway, so before putting the wheels back on in the rear when changing the endlinks, I wanted to try something. I pushed down on the rotor when the spring perch was unattached and low and behold, there was the clunking noise.
Now that I finally diagnosed the problem, I have a question before I try and fix this. Is there a way to access the bolt holes for the rear-upper shock mount from inside the vehicle - like underneath the trunk carpeting/lining? The reason I ask is because I either need to retap the holes or drill them through and use a nut/bolt to keep this from happening again. I know that the bolts won't go any tighter because I have already tried, hence my need to retap the holes.
I just don't want to have to spend a whole day taking off the rear subframe and junk to find out there was an easier way to access it. I hope you know what part of the rear suspension I am talking about. Any help would be appreciated but I know I have diagnosed the problem to be loose upper shock mounts.
Thanks in advance for your help
